LAVATORY.

To all whom ,it may concern:

Be itknown that I, JOHN MCPHERSON, J r. a citizen of the United States of America', residing at Detroit, in the county of `lfllayne and State of Michigan, have invented certain 'new and useful Improvementscin Lavat-ories,

of which the following is erence being had therein ing drawings.

This invention refers to a lavatory of a portable ty e for use where running water is not availab e, and more especially `to means for sup lying both hot and cold Water, and for disc arging water under v ressure without a specification, refto the acco1npanyapparatus possessing sanitary features which make it suitable for sick room and hospital use, andfor hotels.

- The invention-consists in the matters hereinafter` iset forth,v and more particularly pointed out in the appended claims.

Referring to the drawings, Figure 1 is 'a view in perspective of va lavatory embodying features ofthe invention. Fig. 2 is a View in vertical section, showing a ditlerent form of discharging faucet. Fig. 3 isa view in horizontal section, ta'ken on or about line 2me of Fig. 2, a .sec-tionl line indicating the place at which the view in Fig. 2 is taken.

l As herein illustrated, an outer casing 1,`

referlably of enameled sheet nietalor the slab 2, set bowl 3 and splasher boardl 4, forming its top.

' 'A closed cold water tank 5 is placed within the casing and is preferably supported from the slab,A as by a nip le 6 forming an inlet closed by a removal) e screw plug 7 or the like, andl an open faucet 8 discharging into the set-bowl 3. An air pump cylinder 9 inthe casing, that may conveniently be suspended from the slab, has a piston adapted to be operated by a stem 10 extending through the slab with an appropriately shaped handle 11, and is connected by a properly disposed pi e 12 so that a downstroke of the piston orces air into the tank and, by displacement, a corresponding amount of water into the bowl: `Asecond tank 13 for hot Water is likewise sup orted in the-casing, preferably from the slab y an inlet nipple 14 with closure 15, and faucet 16 discharging into the set bowl. The sides and top of this tank are preferably hollow, and a sheet 17 of asbestos or like non-conducting material isplaced between the upper plate the use of gravity or overiead tanks,-thel l -Specication of Letters Patent.

'i' 1S of the top and the slab 2. A conical wall .i 19 extends from top to bottom of the tank,

and a spiral heating coil 20 within the wall 19 g leads from near the bottoni of the tank into the faucet 16. A second spiral heating coil 21 in the cone 19 connects the upper and lower ends of the tank.` Any convenient form of heatinglneans, as for ekainple, a gas burner 22, adaptedto be connected by flexible tubing-23 to the nearest available gas jet is placed in the lower part of the conical opening in the tank under the coils, the second coil 2T setting up a circulation in the tank whenheated, and the water being'- additionally heated in the discharge coil 20, the latter imparting heat almost immediately to its contents whereby the hot water is available about as soon as the burner is lighted. Apertures, 25 in the tank Wall furnish air for the burner. If gas is not convenient, any suitable form substituted.

The hot water tank by a pipe 26 with a second air 27. The piston 28, similar to that 1n the cyl, inder 9, hasthe usual .cupped flexible packing disk 29, and a stern 30 projecting through the slab with handle 31. Check valves 32 are placed in the pipes 12 and 26, to close on the pump up-stroke. To revent the from diying, the cylinders of both are preferably immersed in the cold water tank.

pump. cylinder Fig. -1, or provided with closures having operating handles 33, as indicated in Fig. 2. A waste Apail 34 is likewise provided to receive water from the bowl drain, doors 35 in the casing giving easy access to the interior.

In. operation, if the open cocks are used, a single down-stroke of either pump forces a -good supply of vwater into the bowl from the res ective tanks. lf the cocks are of the olosab e type the air in each tank may be compressed by the pumps to sufficient extent to iill the bowl a number of times.

In either form of construction, a sell'- contained portable lavatory is obtained which may be designed to present a pleasing exterior, and which .is free from all exterior fitting. The heating arrangement, withthe air space around the' hot water tank, precludes any injury or danger from overheating and the apparatus is readily kept in packing of the air pumpI is connected at its top clean, sanitaryk condition, fitting it especially for country houses and hotels, and for hospitals.

Obviously, changes in the details of construction may be made without departing from the spirit of the invention and l do not care to limit myself to any particularform vao or arrangement of parts.

What l 'claim as my invention is:-.

1. A ortable lavatory comprising a casing having a set bowl in its top, water tanks in the casing having connections discharging into the bowl, means for heating the con- .tents of one of the tanks, and means for forcing water from the tanks into the bowl by displacement with air.

2. A portable lavatory comprising a casing having a set bowl in its top, water tanks in the casing having connections discharging into the bowl, means in the casing for forcing air under pressure into each tank, and means for heating the contents of one of the tanks Within and below said tank.

3. 'A portable lavatory comprising a casing having a slab and set bowl forming its top, Water tanks in the casing having connections discharging into the bowl, air pumps in the casing each adapted to force air into one of the tanks, and means within the casing for heating thecontents of one of the l tanks.

V4. A portable lavatory comprisiing a'casing having a slab and 'set bowl forming its top, a air of water tanks suspended under the sla by connections discharging into the bowl, air pumps inclosed in one tank adapted to force air into the tanks, and means for .heating the contents of oine of the tanks.

and a burner for heating the coils.

, 6. vA portable lavatory comprising .la cas-I' ing having a slab and set bowl forming its top, a pair otwater tankssuspended under the slab by connections discharging into the bowl, air pumps inclosed in one tan and a burner for heating the coils 7. A portable lavatory comprising a easadapted to force air into the tanks, one of said tanks having water pipe coils exposed to the air,

ing closed at its top by a slab and set bowl,

closed water tanks in the casing, a faucet for each tank discharging into the bowl, one of said tanks having double top and side walls, an air pump connected to each tank adapted to force air into the tank, one of said tanks having a conical wall forming an air passage from bottom to top of the tank, water pipe coils within the conical Wall communieating with the interior of the tank, and means for heating the coils.

8,` A portable lavatory comprising-a casing closed at its to p by a slab and set bowl,

yclosed water tanks in the casing, a faucet for each tank discharging into the fbowl, one of said tanks having double top and side walls, an air pump connected to each tank adapted to force airinto the tank, one of said tanks having a conical wall forming an air passage from the bottom of the tank to the air space in the hollow top wall thereof, a circulating heating coil in the conical wall opening into the tank 'near its bottom and its top, a discharge heating .coil in the conical wall connecting the tank near its bottom with the faucet and azburner Within the conical wall under the coils.

ln testimony whereof l affix my signature in presence of two witnesses.
